spring-boot - 如何实现动态@ConfigurationProperties 前缀

Question

我需要将动态环境名称作为配置属性的前缀传递。我将从命令行将环境作为 VM 参数传递，并且应该为该环境加载所有属性。

我的配置 :

@Configuration
@EnableConfigurationProperties
@PropertySource("environmentDetails.yml")
@ConfigurationProperties(prefix="${environment}")
public class ConfigurationBean {

    private String brokerUrl;
    private String queueName;
    private String receiverUserName;
    private String receiverPassword;

    public String getBrokerUrl() {
        return brokerUrl;
    }
    public void setBrokerUrl(String brokerUrl) {
        this.brokerUrl = brokerUrl;
    }
    public String getQueueName() {
        return queueName;
    }
    public void setQueueName(String queueName) {
        this.queueName = queueName;
    }
    public String getReceiverUserName() {
        return receiverUserName;
    }
    public void setReceiverUserName(String receiverUserName) {
        this.receiverUserName = receiverUserName;
    }
    public String getReceiverPassword() {
        return receiverPassword;
    }
    public void setReceiverPassword(String receiverPassword) {
        this.receiverPassword = receiverPassword;
    }
}

environmentDetails.yml

spring:
  profiles.active: default
---
spring:
  profiles: default

environment:
  brokerUrl: http://ip:port
  queueName: testQueue
  receiverUserName: testuser
  receiverPassword: password

这是问题:您不能将 .yml 与 @PropertySource 一起使用:boot-features-external-config-yaml-shortcomings

YAML files can’t be loaded via the @PropertySource annotation. So in the case that you need to load values that way, you need to use a properties file.

您必须转换为 .properties 才能执行此操作。
